apertures, leak. or other openings in metallic vessels 0 her articles or metallic apparatus, for forming a filler, plug or closure,

and to the process of making the same.

The principal object of the invention is to provide a composition of matter or metallic compound adapted to be moistened and allowed to harden, or in fact moistened and allowed to harden, said compound being adapted to be handled, and kept, or transported, in dry, comminuted or powdered form until it is to be used, then moistened and while in the form of a paste applied to an aperture, or apertures, leaks, or other openings in metallic vessels or other metallic articles or apparatus, boilers, pipes, or the like, and allowed to harden and form a y i liquid or steam tight plug or closure.

v The invention consists in the process and metallic compound or composition of matter hereinafter described and claimed.

In making and using my improved compound or com osition of matter I provide in pulverized, isintegrated or comminuted form and thoroughly mix in preferably the proportions indicated, the following ingredients or elements: metallic iron seventy-eight parts; iron sulfa e eigi par s; calcium sulfate. )sum or laster of aris mam nt two parts; 'ra iilte or ac ea tw arts; and prefer ha ly also ElllCi of soda three parts. 4 These are thoroug y mixe w ile in powdered, pulverized, disintegrated or comminuted form and preferably dry, and the composition of matter thus provlded is kept in dry and powdered form until it is to be used. It is then moistened by adding and thoroughly intermixing therewith a sufficient quantity of water to reduce it to the consistency of a paste, and in this form it is inserted or applied to an aperture, leak, joint, or other opening or space to be filled in a metallic vessel, boiler, pipe, or other metallic apparatus, article or part and allowed to harden and become dry, forming an air, water and steam tight plug, seal or closure of sufficient strength to withstand so the pressure of steam or other fluid or liquid and prevent the escape thereof. Apertures in metallic plates may thus be effectually closed and metallic articles, and apparatus efficiently mended and rendered fit for use after being damaged, injured or worn. The pipes of boilers may be plugged or mended without removal, and the compound or composition of matter is well adapted for other uses which will be apparent to those versed in the art to which the invention relates.

The above ingredients or elements mixed in the manner and in substantially the proportions above described constitutes or embodies my invention in its referred form, but I do not confine myself to these exact elements or these exact proportions except as set forth in the claims, and I contemplate the use of equivalents such as may be used without departing from the spirit and nature of my invention as herein described 'and claimed.

While I prefer to use silicate of soda, it is possible to use other silicates, such, for instance, as sand in lieu thereof, and good results may be obtained from using the other ingredients without either silicate of soda or sand. Calm- F13 oxid or d of i on may be use in 1eu o 1ron su a e, oug I prefer iron sulfate. Calcium oxid may be used instead of hydrau 1c or or and cement though I prefer the hydraulic cement.

um or d or both in combinaion may e use ms ea of graphite, though I prefer the latter, and better results are believed to follow using the ingredients or elements in substantially the proportions and mixed and prepared and used in the manner described above in the first instance.

In mixing the ingredients it is necessary to add the comminuted elements first and then the liquid, as described, but the pulverizing and mixing may be accomplished in any ordinary manner so far as the means for disintegrating the material or mixing the parts is concerned. Any desired form of pulverizing or mixing apparatus may be employed, and it is there ore not deemed necessary or desirable to illustrate the apparatus herein. 1 1 0 I claim:

1. The process of making an improved metallic compound or composition of matter which consists in mixing in comminuated, disintegrated or pulverized form metallic iron, iron sulfate, calcium sulfate Portland cement, and graphite, then moistening said elements by adding and thoroughly intermixing therewith a suflicient quantity of liquid to form a paste, and then allowing the composition to harden and become dry.

2. The process of making an improved metallic compound which consists in mixing in comminuted form seventy-eight parts of metallic iron, eight parts of ironsulfate, seven parts of calcium sulfate, three parts of silicate of soda, two parts of hydraulic cement, and two parts of graphite, then adding and intermixing therewith a suflicient quantity of water to form a paste, and then alliowing the compound to harden and become 3. The composition of matter forming a metallic compound which com rises metallic iron, iron sulfate, calcium sul ate, hydraulic cement, and graphite all intermixed in comminuted form.

4. The composition of matter forming a metallic compound which comprises seventyeight parts metallic iron intermixed in comminuted form with iron sulfate, calcium sulfate, hydraulic cement and graphite, all in pulverized or powdered form.

5. The composition of matter which consists of metallic iron, iron sulfate, calcium sulfate, silicate of soda, hydraulic cement, 211d graphite all intermixed in powdered orm.

6. The composition of matter which consists in seventy-eight parts of metallic iron, eight parts of iron sulfate, seven parts of calcium sulfate, intermixed with hydraulic cement and graphite, all in comminuted form.

7. A composition of matter which comprises iron sulfate, calcium sulfate, a heavy body-forming element, and hydraulic cement.

8. A com osition of matter which comprises meta lic iron, iron sulfate, calcium sulfate, and cement.

9. A composition of matter which comprises metallic iron, iron sulfate, an alkaline silicate, and hydraulic cement.
